We are remodeling our kitchen. When we opened one of the walls that adjoins a bathroom, we found water damage. It seems that every time the bathroom sink was used, water would leak inside the wall. The drywall and studs have mold on them. I know we need to get rid of the mold.

Since ancient times, people have been very resourceful at trying to reduce mould problems. Until recently, it was believed that such measures as lighting a room with extra-powerful lamps or treating moulds with urine and glue can help to prevent mould growth.
